Technical Field

[0003] This application relates to the field of air handling equipment technology, and more particularly to a ceiling-mounted air conditioner. Background Technology

[0004] Air conditioners are common household appliances. They are categorized into floor-standing, wall-mounted, and ceiling-mounted types based on their installation method. Ceiling-mounted air conditioners, installed in the ceiling, make full use of ceiling space and are therefore widely used.

[0005] In an air conditioner of a related technology, the air guide panel is provided with air outlets on the side wall and the bottom wall respectively. After heat exchange, the air can be output from the bottom or side air outlets to achieve bottom and side air outlets, thereby increasing the coverage area of ​​the air outlet.

[0006] However, in actual use, after the air is heated, the heated air will flow from the air supply channel toward the air outlet below. As for the side air outlet, the air outlet has a different air supply direction than the air supply channel, resulting in a lower air velocity and a smaller air supply range.

[0007] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0011] Panel assembly, the panel assembly comprising:

[0012] The panel has an air inlet and a first air outlet at its bottom, and a second air outlet at its side. The first air outlet is located outside the air inlet.

[0013] An air guide plate is rotatably disposed in the first air outlet;

[0014] The panel is located at the bottom of the housing and covers the mounting opening; the air inlet is connected to the air inlet channel; and the first air outlet is connected to the air supply channel.

[0015] The panel has an air guide section between the first air outlet and the second air outlet, and the air guide section has a connecting port that communicates with the air supply channel.

[0016] A first air outlet is formed on one side of the air guide, and a second air outlet is formed on the other side of the air guide. The first air outlet is connected to the air supply channel through the first air outlet, and the second air outlet is connected to the connecting port through the second air outlet channel.

[0017] Along the air outlet direction, the cross-sectional area of ​​the second air outlet duct tends to decrease.

[0045] In some embodiments, the ceiling-mounted air conditioner of this application includes a housing and a heat exchanger, a fan and a drip tray disposed in the housing. The heat exchanger has an annular structure to surround the outside of the fan. The surrounding of the heat exchanger forms an air inlet channel. An air supply channel is formed between the heat exchanger and the inner wall of the housing. The drip tray is located at the bottom of the heat exchanger for collecting the condensate from the heat exchanger.

[0046] The bottom of the housing is normally open to form a mounting port, which allows the heat exchanger, fan and water tray to be assembled into the housing.

[0047] Ceiling-mounted air conditioners also include a panel assembly, which has an air inlet and an air outlet. The panel assembly is located at the bottom of the outer casing and covers the mounting opening. The air inlet is connected to the air intake duct.

[0048] During use, after the fan starts running, outside air enters the air intake channel through the air inlet. After the air exchanges heat with the heat exchanger, the heat-exchanged air is delivered from the air supply channel to the air outlet. Finally, the heat-exchanged air is output to the indoor space from the air outlet.

[0049] In one embodiment of this application, to increase the coverage of the air supply, the panel assembly 4 is structurally improved as follows. An embodiment of this application provides a ceiling-mounted air conditioner, comprising:

[0050] The outer casing 1 has a mounting opening at its bottom and an air supply channel and an air inlet channel inside, as shown in Figures 1-2.

[0051] Heat exchanger 2, which is configured to perform heat exchange on the flowing air, is disposed in the housing 1, as shown in Figures 3-4;

[0052] Panel assembly 4 is disposed at the bottom of the housing 1, as shown in Figures 1-2.

[0053] Referring to Figures 1 and 3, the panel assembly 4 includes: a panel 41, the bottom of the panel 41 is provided with an air inlet 411 and a first air outlet 412, the side of the panel 41 is provided with a second air outlet 413, and the first air outlet 412 is arranged outside the air inlet 411.

[0054] The panel assembly 4 includes: an air guide plate 42, which is rotatably disposed in the first air outlet 412;

[0055] The panel 41 is located at the bottom of the housing 1 and covers the mounting port, the air inlet 411 is connected to the air inlet channel, and the first air outlet 412 is connected to the air supply channel.

[0056] Referring to Figures 6, 9 and 11, the panel 41 has an air guide 414 between the first air outlet 412 and the second air outlet 413. The air guide 414 has a connecting port 4141, which is connected to the air supply channel.

[0057] A first air outlet 4120 is formed on one side of the air guide 414, and a second air outlet 412 is formed on the other side of the air guide 414. The first air outlet 412 is connected to the air supply channel through the first air outlet 4120, and the second air outlet 413 is connected to the connecting port 4141 through the second air outlet channel.

[0058] The panel vents air outward from the bottom of the panel 41 through the first air outlet 412 and from the side of the panel 41 through the second air outlet 413. In some embodiments, the panel assembly 4 forms vertically arranged air outlet areas on the panel 41 through the first air outlet 412 and the second air outlet 413.

[0059] The first air outlet 412 is located at the bottom of the air supply channel and is connected to the air supply channel. The first air outlet 412 and the second air outlet 413 are separated by a guide section 414. The second air outlet 413 is connected to the air supply channel through a connecting port 4141 provided on the guide section 414.

[0060] The airflow after heat exchange in the heat exchanger 2 is transported downward in the air supply channel. The heat-exchanged airflow can be discharged downwards from the bottom of the panel 41 through the first air outlet 412. At the same time, the airflow transported in the air supply channel flows to the air guide 414 and can also be transported towards the second air outlet 413 through the connecting port 4141, so as to be discharged outwards through the second air outlet 413.

[0061] Since the second air outlet 413 discharges air horizontally, while the airflow in the air supply channel flows vertically downward, in order to increase the air outlet speed of the second air outlet 413 and increase the coverage of the airflow output by the second air outlet 413, the air outlet cross-sectional area of ​​the second air outlet duct tends to decrease along the air outlet direction of the second air outlet duct.

[0062] Specifically, during the air supply process, when it is necessary to deliver heat-exchange airflow to the outside through the second air outlet 413, the air outlet area of ​​the first air outlet 412 can be reduced or the first air outlet 412 can be closed by using the air guide plate 42. In this way, the airflow delivered by the air supply channel enters the second air outlet channel through the connecting port 4141.

[0063] As the cross-sectional area of ​​the second air outlet decreases, the airflow velocity increases during the flow of the air in the second air outlet, resulting in a larger airflow velocity output from the second air outlet 413 to increase the air outlet coverage of the second air outlet 413.

[0064] In some embodiments, referring to FIG12, the top 4131 of the second air outlet 4130 extends sloping downwards toward the second air outlet. For example, the inner side of the housing 1 forms the top 4131 of the second air outlet 4130. This prevents upper airflow from blowing directly onto the ceiling, causing condensation and long-term mold growth. In further embodiments, the top 4131 of the second air outlet 4130 is straight and extends sloping downwards. In other embodiments, the top 4131 of the second air outlet 4130 is arc-shaped and extends sloping downwards.

[0065] By providing an air guide section 414 on the panel 41, the guide section separates the first air outlet 412 and the second air outlet 413. Furthermore, the air guide section 414 is provided with a connecting port 4141 to allow the second air outlet 413 to connect with the air supply channel through the connecting port 4141. The first air outlet duct 4120 and the second air outlet duct 4130 are formed on both sides of the air guide section 414, respectively. For the second air outlet duct 4130 connected to the second air outlet 4130, the air outlet cross-sectional area of ​​the second air outlet 4130 tends to decrease. In this way, the airflow flowing into the second air outlet duct 4130 through the connecting port 4141 of the exhaust channel can be accelerated to increase the air outlet speed of the second air outlet 413, thereby increasing the air supply range.

[0066] In some embodiments, the air supply channel is formed between the heat exchanger 2 and the inner wall of the outer casing 1, and the air inlet channel is formed around the heat exchanger 2.

[0067] In some embodiments, the ceiling-mounted air conditioner also includes a fan 3 located within the air intake duct.

[0068] In one embodiment, the air guide 414 extends outward at an angle from top to bottom.

[0069] Specifically, the air guide 414 provided on the panel 41 is in an inclined extension state, with the upper part of the air guide 414 extending to the lower outer edge of the air supply channel, and the lower part of the air guide 414 extending inclined outward.

[0070] In this way, after the airflow delivered by the air supply channel flows to the bottom panel 41, on the one hand, the airflow can be output from the first air outlet 412, and on the other hand, the airflow tends to flow outward under the guidance of the air guide 414, which makes it easier for some airflow to flow to the second air outlet 413 through the connecting port 4141.

[0071] Furthermore, even when both the first air outlet 412 and the second air outlet 413 are open and supplying air outward, the second air outlet 413 can still have sufficient airflow to provide the airflow volume of the second air outlet 413, thereby greatly increasing the air supply coverage of the second air outlet 413.

[0072] By providing an air guide section 414 on the panel 41, the guide section separates the first air outlet 412 and the second air outlet 413. Furthermore, the air guide section 414 is provided with a connecting port 4141 to allow the second air outlet 413 to connect with the air supply channel through the connecting port 4141. The air guide section 414 extends outward at an angle from top to bottom, allowing the airflow delivered by the air supply channel to flow from the connecting port 4141 into the side of the air guide section 414 near the second air outlet 413, thereby increasing the air volume from the second air outlet 413 and thus increasing the air supply range.

[0073] In one embodiment, the connecting port 4141 is arranged opposite to the second air outlet 413; the connecting port 4141 is configured to deliver airflow toward the second air outlet 413.

[0074] Specifically, for the airflow flowing from the connecting port 4141 towards the second air outlet 413, in order to reduce the airflow resistance within the second air outlet duct 4130, the connecting port 4141 and the second air outlet 413 are arranged in a relatively opposite manner. In this way, after the airflow enters the connecting port 4141, it can flow towards the second air outlet 413, thereby increasing the airflow velocity at the second air outlet 413.

[0075] By arranging the connecting port 4141 opposite to the second air outlet 413, the airflow input from the connecting port 4141 can flow towards the second air outlet 413, thereby improving the air outlet efficiency of the second air outlet 413. Especially when the guide plate 42 closes the first air outlet 412, the guide section 414 guides the airflow output from the air supply channel to the connecting port 4141, allowing the airflow to flow more smoothly from the connecting port 4141 towards the second air outlet 413.

[0076] In one embodiment, the air guide portion 414 is further provided with a bending portion 4142, which bends upward and extends, and the edge of the bending portion 4142 forms a second air outlet 413 between the panel 41.

[0077] Specifically, in order to better guide the airflow toward the second air outlet 413, when the airflow delivered by the air supply channel enters the second air outlet 4130 through the connecting port 4141, the airflow direction in the air supply channel and the air outlet direction of the second air outlet 413 are arranged alternately, that is, at a certain angle. Therefore, the airflow entering the second air outlet 4130 through the connecting port 4141 still has a downward flow tendency. For this reason, a bend 4142 is formed at the lower part of the air guide 414 to guide the airflow input through the connecting port 4141.

[0078] The bend 4142 extends upward at an angle toward the second air outlet 413 so as to guide the airflow smoothly toward the second air outlet 413.

[0079] By additionally providing an upwardly extending bend 4142 on the air guide 414, the bend 4142 extends toward the second air outlet 413, thereby causing the airflow delivered through the connecting port 4141 to flow toward the second air outlet 413 under the guidance of the bend 4142, so as to further improve the air outlet efficiency of the second air outlet 413.

[0080] Referring to Figure 6, in one embodiment, a plurality of parallel stiffening plates 415 are also provided at the second air outlet 413. The stiffening plates 415 are arranged vertically and are connected between the panel 41 and the bent portion 4142.

[0081] Specifically, the second air outlet 413 on the panel 41 has a strip-shaped structure. In order to make the air volume distribution at different positions of the second air outlet 413 uniform, multiple stiffeners 415 are arranged sequentially on the panel 41 along the length of the second air outlet 413. The stiffeners 415 can divide the airflow into the second air outlet 413 to ensure that the air volume at different positions of the second air outlet 413 remains basically uniform.

[0082] By adding multiple parallel stiffeners 415 at the second air outlet 413, the vertical arrangement of the stiffeners 415 can guide the airflow to the second air outlet 413. At the same time, under the action of multiple stiffeners 415, the airflow can be divided to ensure that the airflow output from the second air outlet 413 is evenly distributed.

[0083] Referring to Figures 11-12, in heating mode, due to the large air volume and high wind speed of the first air outlet 412, a negative pressure is formed inside the second air outlet 4130, and the second air outlet 413 forms an air intake effect. After the airflow passes through the connecting port 4141, it mixes with the hot air to form a uniform airflow effect, thereby reducing the air outlet temperature of the first air outlet and improving the comfort of air delivery without reducing the heating capacity.

[0084] In one embodiment of this application, as shown in Figures 1-2, the ceiling-mounted air conditioner includes: a housing 1, the bottom of which forms an installation opening;

[0085] In some embodiments, referring to Figures 3-4, the ceiling-mounted air conditioner includes a heat exchanger 2 configured to exchange heat with the flowing air, the heat exchanger 2 being disposed in the housing 1; an air supply channel is formed between the heat exchanger 2 and the inner wall of the housing 1, the heat exchanger 2 surrounding an air inlet channel, and a fan 3 being located within the air inlet channel.

[0086] In some embodiments, as shown in Figures 3-4, the ceiling-mounted air conditioner includes a fan 3;

[0087] In some embodiments, referring to Figures 1 and 3, the ceiling-mounted air conditioner includes a panel assembly 4. The panel assembly 4 includes a panel 41, the bottom of which is provided with an air inlet 411 and an air outlet. The air outlet is annular and distributed outside the air inlet 411. The air outlet is configured to communicate with the air supply channel and output airflow that has undergone heat exchange via the heat exchanger 2 from the sides and corners of the panel 41, respectively.

[0088] Specifically, the panel 41 has an annularly distributed air outlet around the air inlet 411, through which the heat-exchanged airflow delivered by the air supply channel can be output outward. Since the air outlet has an annular structure, the air outlet can deliver the heat-exchanged airflow outward from all directions of the panel 41, thereby effectively increasing the coverage of the air outlet to achieve 360-degree comprehensive air supply.

[0089] By forming annularly distributed air outlets on panel 41, during use, the airflow after heat exchange treatment by heat exchanger 2 flows to the air outlets through the air supply channel. Utilizing the annular design of the air outlets, the air outlets can vent outwards from both the sides and corners of panel 41, allowing panel 41 to vent outwards 360 degrees. This solves the technical problem of limited air supply coverage due to no air output at the corners of panel 41. The air outlets can effectively increase the air supply coverage, thereby improving the air supply effect of the ceiling-mounted air conditioner.

[0090] Referring to Figure 8, in one embodiment, a first air outlet 412 is provided on the side of the panel 41, and an auxiliary air outlet 416 is provided at the corner of the panel 41; a rotatable air guide plate 42 is provided in the first air outlet 412.

[0091] The panel 41 is located at the bottom of the housing 1 and covers the mounting port. The air inlet 411 is connected to the air inlet channel. The first air outlet 412 is connected to the air supply channel. The auxiliary air outlet 416 is connected to the air supply channel.

[0092] The first air outlet 412 is configured to communicate with the air supply channel and output the airflow after heat exchange via the heat exchanger 2 from the side of the panel 41;

[0093] The auxiliary air outlet 416 is configured to communicate with the air supply channel and output the airflow after heat exchange via the heat exchanger 2 from the corner of the panel 41.

[0094] Specifically, for the lower surface of panel 41, a first air outlet 412 is provided near the side of panel 41, and an auxiliary air outlet 416 is provided at the corner of panel 41.

[0095] The first air outlet 412 and the auxiliary air outlet 416 are respectively connected to the air supply channel. During use, the heat-exchanged airflow delivered by the air supply channel can be output to the outside through the first air outlet 412 and the auxiliary air outlet 416 respectively. In this way, air can be delivered to the side area and corner area of ​​the panel 41, thereby achieving air supply treatment around the four sides and corners of the panel 41.

[0096] By adding an auxiliary air outlet 416 at the corner of panel 41, and connecting the auxiliary air outlet 416 to the air supply channel, the airflow after heat exchange can also be output outward through the auxiliary air outlet 416, thereby enabling the corner area of ​​panel 41 to supply air outward, which is more conducive to improving the coverage of air supply.

[0097] Referring to Figure 7, in one embodiment, the panel assembly 4 further includes a grille cover 43, which is disposed on the panel 41 and covers the air inlet 411. A first air outlet gap 401 is formed between the side of the grille cover 43 and the panel 41, and the first air outlet 412 is arranged opposite to the corresponding first air outlet gap 401.

[0098] Referring to Figure 7, the panel assembly 4 also includes a grid cover plate 44, which covers the outside of the auxiliary air outlet 416, and a second air outlet gap 402 is formed between the cover plate 44 and the panel 41.

[0099] Two adjacent first air outlet intervals 401 are connected by second air outlet intervals 402 at corresponding corners to form an annular air outlet.

[0100] Specifically, the panel assembly 4 covers the air inlet 411 with a grille cover 43, and a first air outlet gap 401 is formed between the grille cover 43 and the panel 41. The first air outlet 412 outputs airflow outward through the first air outlet gap 401, and a guide plate 42 is also provided in the first air outlet gap 401.

[0101] The auxiliary air outlet 416 is blocked by a cover plate 44. A second air outlet gap 402 is formed between the cover plate 44 and the panel 41. The airflow output from the auxiliary air outlet 416 is output to the outside through the second air outlet gap 402.

[0102] The first air outlet interval 401 and the second air outlet interval 402 are connected to each other so that an annular air outlet is formed on the panel 41 around the air inlet 411 to achieve 360-degree air outlet.

[0103] By adding a cover plate 44, the cover plate 44 can block the auxiliary air outlet 416 at the corner of the panel 41. Under the action of the cover plate 44, the airflow output from the auxiliary air outlet 416 will not blow out vertically but will be output from the edge of the cover plate, so that the corner of the panel 41 can output airflow laterally outward, which is more conducive to improving the coverage of the air outlet.

[0104] In one embodiment, the cover plate 44 is detachably disposed at the corresponding corner of the grille cover plate 43; or, the cover plate 44 and the grille cover plate 43 are an integral structure.

[0105] Specifically, the cover plate 44 can be a separate component or an integral structure with the grille cover plate 43.

[0106] For the independent cover plate 44, it can be installed on the grid cover plate 43 by means of clip-on or screw fixing.

[0107] The cover plate 44 is detachably mounted on the grating cover plate 43, making it convenient for operators to install and remove the cover plate 44. Furthermore, by manufacturing the grating cover plate 43 and the cover plate 44 as a single integrated structure, the installation process of the cover plate 44 can be saved, thereby improving assembly efficiency.

[0108] In one embodiment, the panel 41 may have a second air outlet 413 on its side to meet the requirement of side air outlet of the panel 41. The structural design and air outlet method of the second air outlet 413 can be referred to the description in the above embodiments, and are not limited here.

[0109] In one embodiment, the ceiling-mounted air conditioner further includes a water collection tray 5, which is annular in shape and disposed in the mounting opening. The water collection tray 5 is located below the heat exchanger 2 and above the panel 41.

[0110] The water receiving tray 5 is provided with a first ventilation section 51 at its corner, and the auxiliary air outlet 416 is connected to the air supply channel through the first ventilation section 51.

[0111] Specifically, the water collection tray 5 is installed in the mounting opening of the outer casing 1 and needs to meet the requirement of receiving the condensate from the heat exchanger 2. For this reason, the water collection tray 5 has a ring structure, which can separate the air inlet 411 and the first air outlet 412. Furthermore, since the water collection tray 5 is installed in the mounting opening, on the one hand, the water collection tray 5 needs to avoid the air inlet 411 to ensure that the airflow input from the air inlet 411 enters the air inlet channel. On the other hand, the water collection tray 5 has a first ventilation section 51 at its corner to ensure that the airflow in the air supply channel can flow to the auxiliary air outlet 416 through the first ventilation section 51, thereby meeting the requirement that the auxiliary air outlet 416 can smoothly discharge air.

[0112] By setting a first ventilation section 51 on the water receiving pan 5, the water receiving pan 5 can achieve interconnection between the auxiliary air outlet 416 and the air supply channel formed on the outside of the heat exchanger 2 through the first ventilation section 51 set at the corner. In this way, the air supply channel can supply the heat-exchanged airflow to the auxiliary air outlet 416 through the first ventilation section 51 set on the water receiving pan 5, so as to ensure the smoothness of air supply.

[0113] In one embodiment, a second ventilation section 52 is provided on the side of the water receiving tray 5, and the first air outlet 412 and the second air outlet 413 are connected to the air supply channel through the second ventilation section 52.

[0114] Specifically, since the water receiving tray 5 is located in the installation opening and is separated from the first air outlet 412 and the air inlet 411, a second ventilation section 52 is formed on the side of the water receiving tray 5. The second ventilation section 52 will avoid the first air outlet 412 and the second air outlet 413 to meet the requirement that the first air outlet 412 and the second air outlet 413 are connected to the air supply channel.

[0115] By providing a second ventilation section 52 on the side of the water receiving tray 5, the second ventilation section 52 enables the first air outlet 412 and the second air outlet 413 to connect with the air supply channel, thereby ensuring the smooth airflow of the air supply channel.

[0116] In some embodiments, the first ventilation section 51 and the second ventilation section 52 may be openings through which airflow passes.

[0117] In another embodiment of this application, to avoid condensation from the panel assembly 4, the panel assembly 4 is structurally improved as follows.

[0118] Referring to Figure 3, the panel assembly 4 includes a panel 41, with an air inlet 411 at the bottom and a first air outlet 412 at the side of the panel 41; the panel 41 is located at the bottom of the housing 1 and covers the mounting opening, the air inlet 411 is connected to the air inlet channel, and the first air outlet 412 is connected to the air supply channel.

[0119] Referring to Figures 1, 6 and 7, the panel assembly 4 includes a grille cover 43, which is disposed on the panel 41 and covers the air inlet 411. A first air outlet gap 401 is formed between the side of the grille cover 43 and the panel 41. The first air outlet 412 is arranged opposite to the corresponding first air outlet gap 401.

[0120] Referring to Figure 7, the panel assembly 4 includes a cover plate 44, and a second air outlet interval 402 is formed between the cover plate 44 and the panel 41;

[0121] The first air outlet interval 401 is connected to the adjacent second air outlet interval 402, which is configured to output airflow toward the corresponding corner of the panel 41.

[0122] Specifically, during operation, the airflow delivered by the ceiling-mounted air conditioner flows through the first air outlet 412 and is output outward via the first air outlet interval 401. Since the first air outlet interval 401 and the second air outlet interval 402 are interconnected, during the process of the airflow being output from the first air outlet interval 401, some of the airflow will also flow into the second air outlet interval 402 and flow from the edge of the cover plate 44 toward the corner of the panel 41.

[0123] The airflow output from the second air outlet 402 can blow towards the panel 41, and the airflow can cover the surface of the corners of the panel 41. Under the action of the airflow, the formation of condensation at the corners of the panel 41 is reduced.

[0124] By providing a cover plate 44 on the panel 41, a second air outlet gap 402 is formed between the cover plate 44 and the panel 41 at the corner position. During use, the airflow output from the first air outlet 412 is output to the room through the first air outlet gap 401. The first air outlet gap 401 is connected to the adjacent second air outlet gap 402, so that part of the airflow output from the second air outlet 413 can also flow into the second air outlet gap 402. Then, under the action of the second air outlet gap 402, it flows towards the corner of the panel 41. In this way, airflow also flows through the corner of the panel 41 to reduce condensation at the corner of the panel 41 and improve the user experience.

[0125] Referring to Figures 10 and 13, in one embodiment, a protruding airflow guide 417 is further provided on the outer surface of the panel 41 opposite to the cover plate 44; the airflow guide 417 is configured to guide the airflow from the second air outlet interval 402 toward the corner of the panel 41.

[0126] Specifically, for the airflow flowing between the cover plate 44 and the panel 41, in order to guide the airflow to be output from the second air outlet 402 and evenly disperse the air volume towards the corners of the panel 41, a protruding guide portion 417 is provided on the panel 41. The guide portion 417 extends towards the corners of the panel 41, so that the airflow will be evenly dispersed under the action of the guide portion 417, thereby better covering the corners of the panel 41.

[0127] By forming a guide portion 417 on the surface of panel 41 opposite to cover plate 44, the airflow output from auxiliary air outlet 416 can be guided by the guide portion 417 to be output from the edge of cover plate 44. The guide portion 417 can guide the airflow to flow out smoothly, thereby improving the uniformity of airflow distribution.

[0128] In one embodiment, a recess is formed on the outer surface of the panel 41 opposite to the cover plate 44, and the guide portion 417 is formed in the recess.

[0129] Specifically, a recess is formed on the panel 41 and is arranged opposite to the cover plate 44. The distance between the recess and the cover plate 44 is relatively large to form sufficient space to buffer the airflow. The buffered airflow is diverted by the guide section 417 to ensure that the airflow is uniformly output to the outside from the second air outlet interval 402.

[0130] By forming a recess on the panel 41 to be arranged opposite to the cover plate 44, the airflow can be buffered between the recess and the cover plate 44, and the airflow guide 417 can guide the airflow to be output evenly, so as to improve the anti-condensation treatment capability of the corner of the panel 41.

[0131] In one embodiment, the recessed portion forms an arc-shaped concave surface.

[0132] Specifically, by designing the recessed part as an arc-shaped concave surface, the wind resistance of the arc-shaped concave surface is smaller and it is more conducive to guiding the airflow, thereby improving the smoothness of airflow output.

[0133] In one embodiment, an auxiliary air outlet 416 is provided at the corner of the panel 41, and the auxiliary air outlet 416 is connected to the air supply channel;

[0134] The cover plate 44 covers the outside of the auxiliary air outlet 416.

[0135] Specifically, in order to effectively increase the air volume of the second air outlet interval 402 and thus improve the anti-condensation capability, an auxiliary air outlet 416 is additionally provided at the corner of the panel 41. The auxiliary air outlet 416 can be connected to the air supply channel so that the heat-exchanged airflow delivered by the air supply channel is output through the auxiliary air outlet 416. Under the guidance of the cover plate 44 and the guide part 417, the airflow output from the auxiliary air outlet 416 is directed towards the corner of the panel 41 with a larger air volume, which is more conducive to reducing condensation at the corner of the panel 41.

[0136] The auxiliary air outlet 416 is located in the recess, so that there is a sufficient distance between the auxiliary air outlet 416 and the cover plate 44 to buffer the airflow output from the auxiliary air outlet 416, and then, together with the guide part 417, guides the airflow to be output more smoothly.

[0137] In one embodiment, the panel 41 is provided with a plurality of radially distributed guide sections 417 around the auxiliary air outlet 416, and the guide sections 417 are configured to guide the airflow output through the auxiliary air outlet 416 toward the corner of the panel 41.

[0138] Specifically, when an auxiliary air outlet 416 is provided, the guide portion 417 provided on the recess is arranged around the auxiliary air outlet 416, and multiple guide portions 417 are distributed in a radial pattern around the auxiliary air outlet 416.

[0139] During use, the airflow output from the auxiliary air outlet 416 can be guided by the divergent air distribution guide 417 so that the second air outlet interval 402 outputs airflow evenly, so that the airflow covers the corners of the panel 41 more comprehensively.

[0140] By arranging airflow guides 417 in a radial pattern on the panel 41, multiple airflow guides 417 cooperate with each other to guide airflow to be output evenly from the edge of the cover plate 44, thereby improving the uniformity of airflow distribution in the corner area of ​​the panel 41.

[0141] In one embodiment of this application, as shown in Figures 14-18, an antibacterial module 6 is placed in the water receiving tray 5 to perform antibacterial treatment on the water collected in the water receiving tray 5. To facilitate the later disassembly and maintenance of the antibacterial module 6, the water receiving tray 5 is structurally improved as follows: Specifically, the water receiving tray 5 has a ring structure and is disposed in the mounting port.

[0142] The water receiving tray 5 is provided with an installation and fixing part 53, the antibacterial module 6 is disposed on the installation and fixing part 53, and the side of the outer shell 1 is provided with an openable inspection port 11, which is arranged close to the installation and fixing part 53.

[0143] Specifically, an installation fixing part 53 is provided in the water receiving tray 5 to meet the installation requirements of the antibacterial module 6. In order to facilitate the disassembly and maintenance of the antibacterial module 6, an inspection port 11 is also provided on the outer shell 1, and the inspection port 11 is arranged close to the installation fixing part 53.

[0144] When the antibacterial module 6 needs to be disassembled and repaired, the inspection port 11 on the outer shell 1 can be opened to remove the antibacterial module 6 installed on the mounting and fixing part 53; similarly, the new antibacterial module 6 is placed into the water receiving tray 5 through the inspection port 11 and fixed on the mounting and fixing part 53.

[0145] During maintenance, operators do not need to remove the water tray 5 from the outer casing 1 to repair or replace the antibacterial module 6, which makes it convenient for operators to perform maintenance later.

[0146] By providing an inspection port 11 on the side of the outer casing 1, which is located adjacent to the mounting and fixing part 53 in the water receiving tray 5, when it is necessary to replace or maintain the antibacterial module 6, the operator only needs to open the inspection port 11 to remove the antibacterial module 6 installed in the water receiving tray 5 without having to disassemble the water receiving tray 5. This effectively reduces the maintenance difficulty of the antibacterial module 6, facilitates the replacement of the antibacterial module 6, and improves maintenance convenience.

[0147] In one embodiment, the access port 11 is located on the outside of the mounting and fixing part 53. Specifically, the access port 11 can be provided on the side wall of the housing 1.

During maintenance, the operator can open the access port 11 from the top of the housing 1 to perform maintenance operations on the antibacterial module 6 in the water tray 5.

[0149] In one embodiment, in order to facilitate quick and easy assembly and disassembly of the antibacterial module 6, the antibacterial module 6 is snapped onto the mounting and fixing part 53.

[0150] Specifically, the antibacterial module 6 is fixed to the mounting and fixing part 53 by a snap-fit ​​method, thus achieving a screwless connection. During the assembly and disassembly process, there is no need to tighten the screws, thereby improving the convenience of assembly and disassembly.

[0151] By using a snap-fit ​​method to connect the antibacterial module 6 to the mounting and fixing part 53, it is convenient for operators to snap the antibacterial module 6 onto the mounting and fixing part 53 during assembly, and also convenient for operators to remove the antibacterial module 6 from the mounting and fixing part 53 during disassembly, thus achieving a screwless connection.

[0152] In one embodiment, the mounting and fixing part 53 is provided with a first claw 531, and the antibacterial module 6 is clipped onto the first claw 531.

[0153] Specifically, in order to achieve the snap-fit ​​connection between the antibacterial module 6 and the mounting and fixing part 53, the mounting and fixing part 53 can be engaged with the antibacterial module 6 through the first claw 531.

[0154] The antibacterial module 6 is mounted by setting the first claw 531. When installing the antibacterial module 6, the antibacterial module 6 abuts against the first claw 531, so that the first claw 531 is finally locked on the antibacterial module 6 to facilitate the assembly.

[0155] In one embodiment, the mounting and fixing part 53 is further provided with a positioning post 532, which is arranged on the side of the first claw 531;

[0156] The antibacterial module 6 is provided with a positioning hole 61;

[0157] The positioning post 532 is inserted into the positioning hole 61, and the first claw 531 is engaged with the edge of the antibacterial module 6.

[0158] Specifically, in order to meet the mounting requirements of the antibacterial module 6 by using the first claw 531 set on one side, the mounting and fixing part 53 is provided with a positioning post 532 to cooperate with the positioning hole 61 in the antibacterial module 6 for positioning. In this way, during the installation of the antibacterial module 6, the positioning post 532 is inserted into the positioning hole 61, and the antibacterial module 6 is pressed to the bottom of the water receiving tray 5, so that the first claw 531 is locked on the edge of the antibacterial module 6, thereby completing the mounting assembly.

[0159] By setting a positioning post 532 on the side of the first claw 531, the positioning post 532 is inserted into the positioning hole 61 for positioning during the installation of the antibacterial module 6, so that the first claw 531 can be reliably locked on the antibacterial module 6, thereby improving the reliability of the locking.

[0160] In another embodiment, the mounting and fixing part 53 is further provided with a guide groove 533, the guide groove 533 is arranged vertically, the guide groove 533 is arranged opposite to the first claw 531, and the end of the antibacterial module 6 is located in the guide groove 533.

[0161] Specifically, the edge of one end of the antibacterial module 6 is engaged by the first claw 531, and the positioning post 532 is inserted into the positioning hole 61. To improve assembly accuracy, the mounting and fixing part 53 is also provided with a guide groove 533 to guide the other end of the antibacterial module 6.
